This invention describes a process flow and method to assemble triple IG units without contaminating the center glass lite. A non-contact vacuum pad is used to lift a glass lite off from a horizontal or vertical support that conveys it from a glass washer to an assembly station. Each of multiple pads has a capacity to lift approximately seven to ten pounds. Use of multiple pads per glass sheet or lite allows lites having dimensions up to 70 by 100 inches (assuming glass thickness of one quarter inch) to be assembled.
 Physical reduction to practice of the embodiments disclosed has been performed in part in performance of DOE (Department of Energy) Co-operative Agreement DE-EE000167, W(A)-09-050, CH-1513 between the Department of Energy and GED Integrated Solutions, Inc.
